Richard McClements, interim superintendent of the Windham Southwest Supervisory Union, said Heller resigned in December. McClements said he didn’t know the exact date but that Heller said in his resignation letter that his last day would be Jan. 2.

McClements said Wednesday that he didn’t want to release the letter because it hadn’t been formally accepted by the Readsboro School Board, which will meet next week.

Police said Heller had embezzled grant money from the school and about $200 from a fund used for student lunches.
